Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The aromaticity</bold> of the ring and cage isomer of a hexasilabenzene derivative was investigated by experimentally determined charge‐density distribution. Topological analysis and valence‐shell charge concentrations reflect the degree of delocalization in the various bonds. A transannular Si⁰–Si^I bond was found in the ring conformer, while an interstitial Si⁰–Si⁰ bond along the hub in the silapropellane moiety of the cage conformer was not detected.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1xprfjx5" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
